E20-018 Online Practice Questions and Answers

A customer has asked you to develop a framework for assuming that the cloud Part of this will resume an assessment development.

Where should you lock first for assessment criteria and technologies?

A. International standards

B. Internal IT development

C. Company metadata

D. Industry best practices

A company has finished the design for their VDC. They realize that they should also include a few design considerations to prepare them for cloud.

What is a key business reason for the company to build a cloud-based service?

A. Speed and agility

B. Cost savings

C. Multi-tenancy

D. Chargeback

When should you consider implementing hypervisor over-provisioning?

A. Tier-2 and Tier-3 applications are configured in separate hypervisor clusters.

B. Performance is a primary and critical consideration.

C. Multiple applications have the same peak workload times.

D. A mix of Tier-1 and Tier-2 applications are in the same hypervisor cluster.

Which backup solution(s) should be your preferred choice(s) when you require consistent backups for ease of recovery?

A. VM-based backup and image-based backup

B. Storage-based backup only

C. Hypervisor-based ("VM as flat file") backup

D. Storage-based backup and VM-based backup

Which aspect of data security does TLS address?

A. Secure data transport to and from the application over the network

B. Secure block data transfer between the host and storage array

C. Encryption of data at rest on a storage device

D. Centralized key management for data encryption

As part of a VDC design, you configured a number of hypervisor clusters that require a non-routable network to accommodate data transfers for online VM migrations and cluster heartbeats. However, some of the clusters contain sensitive data that should not be accessible by hypervisors in any other cluster. The design recommends using Private VLANs to isolate each cluster's private network traffic.

The network administrator has created a Primary VLAN, and asks you how the Private VLANs should be configured. How should you instruct the network administrator to proceed?

A. Configure a Community Private VLAN for each cluster.

B. Configure a Community Private VLAN for each cluster, and configure the gateway port in the Primary VLAN.

C. Configure an Isolated Private VLAN for each cluster.

D. Configure an Isolated Private VLAN for each cluster, and configure the gateway port in the Primary VLAN.

You have decided to pursue a "scale-out" approach instead of a "scale-up" approach to storage. What is the fundamental tradeoff that you have made?

A. Complexity of management versus limited scalability

B. Improved availability versus unlimited scalability

C. Higher application throughput versus degraded response time

D. Ease of storage tiering versus unpredictable performance

What are key legal contracts for a service provider?

A. Service Level AgreementTerms of ServiceTermination Agreement

B. Service Level AgreementTerms of ServiceEnterprise License Agreement

C. End User License AgreementTermination AgreementService Level Agreement

D. End User License AgreementTermination Agreement Performance Guaranty

A company wants to ensure that their critical application can fail over to another physical host within the cluster without disruption.

Which feature should be utilized?

A. Online Migration

B. High Availability

C. Fault Tolerance

D. Resource Pooling

A VDC application design dictates the use of multiple hypervisors with array LUNs that are directly provisioned to each VM. The application data has an active lifetime of 6 to 9 months, after which it is rarely accessed. The need is to re-purpose several storage arrays from different vendors and performance capabilities.

Which technology should be considered for the VDC storage design?

A. Block-level storage virtualization

B. File-level virtualization with global namespace

C. Thin-on-thin provisioning

D. Intra-array storage tiering
